Big NDArray generate Operand Tensor meet protobuf exceeded maximum protobuf size of 2GB ?

Hi :
from spark DataFrame generate org.tensorflow.ndarray.DoubleNdArray , after I want to generate Operand[TFloat64] tensor , meet error

scala> val featureVector = SparkConverter.sparkDataframeFeatureVectorConvertTfTensor(finalInputDf,"final_features" )
featureVector: org.tensorflow.ndarray.DoubleNdArray = org.tensorflow.ndarray.impl.dense.DoubleDenseNdArray@e3f6a6a0
scala> val ft  = tf.constant(featureVector)
[libprotobuf ERROR external/com_google_protobuf/src/google/protobuf/message_lite.cc:451] tensorflow.AttrValue exceeded maximum protobuf size of 2GB: 6279090916

  ... 59 elided

but if I filter some small part Dataframe is ok

scala> val featureVector = SparkConverter.sparkDataframeFeatureVectorConvertTfTensor(finalInputDf.filter(col("pay_status").equalTo(1)),"final_features" )
featureVector: org.tensorflow.ndarray.DoubleNdArray = org.tensorflow.ndarray.impl.dense.DoubleDenseNdArray@627077a

scala> val ft_small  = tf.constant(featureVector)
ft_small: org.tensorflow.op.core.Constant[org.tensorflow.types.TFloat64] = <Const 'Const_2'>

scala> ft_small.asTensor().numBytes()
res43: Long = 1058424696

Start with the reported Ops.constant and Constant.tensorOf call path, using the SparkConverter-generated DoubleNdArray and the smaller filtered DataFrame as contrasting inputs. Reproduce the protobuf size failure and determine the expected behavior for tensors above 2GB; the issue does not define a requested change or a clear completion test.
